function [approx] = T_C(angle,counter)
approx=0;
radianangle= angle*pi/180;
polynum=1;
polynum=radianangle;
approx=approx+polynum;
while abs(counter/polynum)<1
n=n+1;
polynum=polynum*-1*anglerad*2/(2*n+1)/(2*n);
approx=approx+polynum;
end
end

Hi John,
I understand you want to find the value of sin(x) using Taylor series expansion. I believe your code should be modified as follows:
polynum=polynum*-1*(anglerad^2)/(2*(n+1))/(2*n);
You could modify the code accordingly for cos(x). You can find the both the Taylor series expansions here: https://en.wikipedia.org/wiki/Taylor_series
